Subject: __GFP_REPEAT usage in fq_alloc_node

Hi Eric,
I am currently checking kmalloc with vmalloc fallback users and convert
them to a new kvmalloc helper [1]. While I am adding a support for
__GFP_REPEAT to kvmalloc [2] I was wondering what is the reason to use
__GFP_REPEAT in fq_alloc_node in the first place. c3bd85495aef
("pkt_sched: fq: more robust memory allocation") doesn't mention
anything. Could you clarify this please?

Thanks!
